Abstract
Compressor rolling piston, including two and half pistons, arranges cavity in each half piston, and the two and half axial interference of piston link into an integrated entity.This utility model, owing to rolling piston is divided into two and half pistons and is linked together by interference, therefore manufactures more convenient.And can select as required in piston cavity, fill the proportion material less than piston material, therefore alleviate the weight of whole piston in guarantee on the premise of, piston can be supported and be unlikely to deform, so that it is guaranteed that properties of product.
Description
Technical field
This utility model relates to a kind of compressor part.
Background technology
Rotary compressor for refrigerant, also known as rolling rotor compressor, it utilizes piston rotation to carry out refrigerant gas
Compression, has put much years on market, and it is one of the most the most frequently used compressor.
Rolling piston is the strength member of rotary compressor for refrigerant set, and the bias of its eccentric shaft being arranged on compressor turns
On, roll along cylinder wall during refrigeration, slide plate under spring force with the cylindrical wall close contact of rolling-rotor, composition is dynamic
Seal, along with rotary compressor uses novel environment-friendly refrigerant, high efficiency and energy-conservation etc. becomes more diverse, to can be suitably used for height
Rolling piston under the rigor condition such as load, high power, high temperature, high pressure is had higher requirement.
For a long time, rolling piston is solid, and therefore its weight is big.For driving rolling piston to rotate, need to spend relatively
Many energy.But there is higher intensity again, the most up to the present owing to rolling piston needs possess preferable frictional behaviour
The most do not find a kind of effective ways saving energy.
The applicant has obtained the rolling piston of hollow cylinder through research, though it can alleviate weight, reduces energy consumption, but by
Hollow cylinder in existing structure is not easy to manufacture, it is therefore desirable to find the piston of more preferable structure.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art to provide a kind of compressor
With rolling piston so that it is can easily manufacture.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
Compressor rolling piston, including two and half pistons, arranges cavity in each half piston, the two and half axial mistakes of piston
It is full of and links into an integrated entity.
Specifically, according to concrete conditions such as bonding strength and piston sizes, above-mentioned interference connection is arranged on two and half pistons
Outer connecting end surface and/or interior connecting end surface on.
Preferably, the cavity of half piston fills up proportion less than piston material material.
Preferably, above-mentioned substance is resin or plastics, can conveniently inject cavity.Obviously, above-mentioned substance is alternatively other classes
Material like character.
Preferably, above-mentioned substance is the resin that with the addition of firming agent, so can inject at normal temperatures and solidify.
Compared with prior art, the utility model has the advantage of: owing to rolling piston is divided into two and half pistons and passes through
Interference links together, and therefore manufactures more convenient.Proportion in piston cavity is also had to be less than the material of piston material, therefore
On the premise of guarantee alleviates the weight of whole piston, piston can be supported and be unlikely to deform, so that it is guaranteed that properties of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment rolling piston.
Fig. 2 is the structural representation of another embodiment rolling piston of this utility model.
Fig. 3 is the structural representation of this utility model another embodiment rolling piston.
Fig. 4 is the structural representation of this utility model another embodiment rolling piston.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Embodiment 1, as it is shown in figure 1, compressor rolling piston, is arranged including in half piston 2, half piston 1, half piston 2
Cavity 21, arranges cavity 11 in half piston 1, logical between contact position inside and outside the axial biend 13,23 of half piston 2 and half piston 1
Interference connects 4 and links together.
Above-mentioned cavity 21 and cavity 11 are located on connecting end surface for annular and opening, and such half piston easily manufactures.
Embodiment 2, as in figure 2 it is shown, the outer shroud of half piston 2 connects end 23 and second half piston outer shroud connects to enter between end 13
Row interference connects 4, and remaining is with embodiment 1.
Interference is carried out even between end 23 and second half piston 1 outer shroud connection end 13 owing to the outer shroud of only half piston 2 connects
Connect 4, so manufacture simpler.
Embodiment 3, as it is shown on figure 3, the internal ring of half piston 2 connects end 23 and second half piston 1 internal ring connects between end 13
Carrying out interference and connect 4, remaining is with embodiment 1.
Embodiment 4, as shown in Figure 4, arranges through hole 12 on half piston 1, arranges through hole 22, by through hole on half piston 2
Resin 5 is filled up in the cavity of hollow cylinder by 22, and remaining is with embodiment 1.
Certainly, it is possible in the cavity that by through hole 21 resin filled up hollow cylinder.Half piston 1 can also be utilized with another
Space casting resin 5 between half piston 2.
